M CARTNEY ATTORNEY Patented Mar. 16, 1954 UNI TED STATES PATENT OF F I CE 2,672,113 INJECTOR-[HECTOR BOAT- CLEANER Geoifi'eyLaMcCartney, Atlanta, Ga. Application December 6, 1950, Serial N o.-199,439 2 Claims (Cl. 114185) My invention relates to boat cleaners generally' but more in particular to an injectorejector boat cleaner which usesthe force of water moving through the same either to bring water into the boat or to remove the water from the boat.

The operation of removing water fromboats is well known in the prior art and has-necessitated the use of divers bailing mechanismsranging from hand operated devices to elaborate pumping systems. Considerable effort has also been put forthto provide owners of smallboats with hand pumps and light power-operated mechanisms serving not only to draw waterfor cleaning purposes but also acting as a means of removing the waterwhichhas either leaked in or been deliberately placedinthe-boat for cleaning. The disadvantage of most of thesesystems lies not only in the expense to the" small boat owner, but also in the fact" that the device is usually cumbersome andmust be-handled and lifted from one end ofthe boat to theother to relieve the various compartments of water or bilge.

It is an object of the present invention to provide an automatic pump, operated by water in which the boat is moving, to draw'a'ccumulatedwater from oil" the insidebottom o" the boat or to bring in other waterfor cleaning the boat at the will of the operator.

It is another object of the invention to provide such a pumpwhich is inexpensive-tomanufacture and which gunwale of any small type craft.

It is a further objectofthe inventionto provide an injector-ejector pump. for small'fis'hing boats which may be hingedto the gunwale of the boat so that the same may be let into the water for use in either bringing water into the boat or removing water from the boat, and which may be folded or hinged inside the boat when not in use.

Further objects and advantages of the invention will become apparent in the course of the following detailed description when viewed together with the accompanying drawing in which:

Fig. 1 is a front end view of av boat cleaning device made in accordance with the teachings of the present invention, the same being shown as attached to the gunwale of a small boat.

Fig. 2 is a side elevational view of the device shown in Fig. 1.

Fig. 3 is a broken side view of a tube member of the invention, the same being shown closed to water passing therethrough.

Fig. 4 is a broken rear View of the illustration shown in Fig. 1.

mayv be'secured'ifor use to the In the drawing, numeral 10 designates a'boat of the shape generally conforming to that of the conventional small fishing boat.

My invention is adapted tobe positioned on the gunwale II of the boatby means of two U- shaped metal brackets I2 and I3 bent to conform more or lessto the inside batten or shear clamp 14 and wedged against the same by means of jack screws l5. The brackets are spaced apart in the manner shown, and each is provided with one long upper leg l6 extended horizontally out over the boat gunwale II, the legs being bent in-the manner shown so as to stand fiatwise vertically. Pivotally attached respectively to these legs are metal strips l1 and It, the lower ends ofwhich are bent around and bolted or otherwise affixed to a length of tubing material constituting a Venturihousing designated generally by the numeral l 9.

The-housing l9 consists of tubing material of any desired size with preferably a truncated cone or funnel-shaped leading end 20. The opposite end of the housing I9 is provided with a transverse slot 2| cut through onlya portion of the tube and adapted to slidably receive a valve plate 22. The valve platen, in the present instance, is-kept from being lost by attaching the same tothe tube end bymeans of a chain 23.

As shown in Fig. 2, I have prepared asecond length of tubing 24 which completes the Venturi action as will be described later. This tube 24-is-set throughthe topwall of'the housing l9 with the lower end terminating on the longitudinal axis and'being beveled as shown. The tube 24 is set at a'low angle and has its-upper end prepared to receive a length of flexible hose 25 which is of sufficient length to reach any of the compartments along the length of the boat defined by the boat ribs.

For a description of the device as a means of drawing water from a boat, reference is directed to Fig. 2 which shows the boat l0 riding in water 26 and being provided with my invention attached to its gunwhale II with the cone end 20 of the Venturi housing 19 facing the forward end or bow of the boat. The valve plate 22 is removed from its slot 2! to allow water to pass through the Venturi housing [9.

Let it be assumed that a quantity of water is inside the boat, whether from a leak in the boat bottom, or whether put there deliberately by the boat operator for cleaning purposes. Withthe device positioned as shown, it is readily apparent that forward movement of the boatv will cause water to move through the housing I9 from front to rear, thus creating a draft or suction through the tube 24, the amount of suction being governed by the speed of the boat through the water. The boat operator, by means of the flexible hose, may suck or drain any or all of the compartments in the boat while the boat is being propelled through the water, without resorting to docking his boat or turning the same upside down on the shore.

Now let it be assumed that the boat operator desires to bring water into the boat for cleaning or rinsing purposes. By placing the valve plate 22 into its slot 2| in the housing l9, water is prevented from going throughthe housing 19 and is forced, by the movement of the boat, upwardly into the smaller tube 24 and'through the flexible hose 25 as shown in Fig. 1. As soon as sufficient water has been forced into the boat, the operator may then remove the valve plate 22, which immediately starts the sucking action to drain the water from the boat in the manner described above.

The device'is simple in its construction and easy to manufacture. When not in use the Venturi mechanism may be hinged over the gunwhale to hang inside the boat or may be removed completely by'loosening the jack screws IS. The device as shown and described is readily adapt able to various small craft, and the length of the depending strips H and 58 may be made to hold the housing l9 below the water line of boats of many sizes.

The device is highly advantageous to fishermen using small boats wherein all equipment, tackle and even the fish are placed on the floor boards of the boat until the boat is finally docked for cleaning. Since the device not only injects water into the boat, but also ejects the same water, the fisherman is permitted to clean the boat perfectly while bringing it to the dock after his trip.

It will be obvious that my invention provides a needed article of great convenience and usefulness, and that while I have illustrated and described my invention in a very practical embodiment without attempting to show other embodiments, various modifications and changes may be made without departing from the scope of my invention as defined in the appended claims.

I claim:

1. Injector-ejector type apparatus for cleaning a boat while the boat is moving through water comprising, an elongated hollow housing, means for suspending said housing from the gunwhale of a boat so that water will enter through the forward end of said housing as the boat moves forward through the water, a small hollow tubular member projecting through a wall of said housing at an acute angle with respect to the longitudinal axis of said housing at a point spaced from the ends of the housing and having the lower end of the member lying substantially along the. longitudinal axis of said housing, fiexlble hose means connected to the upper end of said tubular member, and valve means adjacent and connected to the trailing end of said tubular member, said valve means being selectively operable to block the flow of water from the trailing end of said tubular housing and inject water from within said housing upwardly through said tubular member when closed and to open the trailing-end of said housing for the flow of water therefrom when open so as to eject water downwardly through said tubular member.

2. Injector-ejector type of apparatus for cleaning a boat while the boat is moving through water comprising, a hollow tubular housing having a trailing end and an enlarged funnel-shaped forward end, means for suspending said housing from a boat so that water will enter the forward end of said housing as the boat moves forward through the water, a smaller hollow tubular member projecting through a wall of said housing at an acute angle with respect to the longitudinal axis of said housing at a point spaced from the ends of the housing and having the lower end of the member beveled to lie substantially along the longitudinal axis of said housing, flexible hose means connected to the upper end of said tubular member and extended into the bilge portion of the boat, and valve means adjacent and connected to the trailing end of said tubular member, said valve means being selectively operable to block the flow of water from the trailing end of said tubular housing and inject water from within said housing upwardly through said tubular member when closed and to open the trailing end of said housing for the flow of water therefrom when open so as to eject water from within said boat outwardly through said tubular member.
